ST. PAUL, Minn. (AP) -- A company with three manufacturing plants in southern Minnesota wants a change in state law in order to shield itself from future asbestos claims.

Crown Holdings Inc. says its 1963 merge with a rival company left it with assets as well as liabilities of its acquisition, even though Crown never directly manufactured asbestos.

Attorney Mark Behrens says Crown had no idea its $7 million deal would eventually result in $700 million in litigation costs as a result of asbestos claims. The Philadelphia can manufacturer has successfully argued for the law change in 15 states, including Wisconsin.

Opponents say a change in state law would allow the company to skirt its legal obligations. The Star Tribune says the state Senate could vote on the matter as early as Thursday.
